OVERVIEW
The ZM5304 Modem is a fully integrated module with an on-board antenna that allows the establishment of a Z-Wave network
with minimum risk. The SD3503 modem chip is used with an external NVM (EEPROM), 32MHz crystal, power supply decoupling,
SAW filter, matching circuit, and a helical antenna. Figure 2.1 shows the main blocks of the ZM5304 Modem, while Figure 2.2
illustrates the firmware stack of an example application.

2.1 PERIPHERALS
2.1.1 ADVANCED ENCRYPTION STANDARD SECURITY PROCESSOR
The Z-Wave protocol specifies the use of Advanced Encryption Standard (AES) 128-bit block encryption for secure applications.
The built-in Security Processor is a hardware accelerator that encrypts and decrypts data at a rate of 1 byte per 1.5µs. It encodes
